Theoretical Physics

Theory scribbling
  • What happened in the early Universe?

  • What is Dark Matter?

  • How do elementary particles build up the world we know?

  • Which elementary particles remain undiscovered?

  • Why is time irreversible?

These are questions that we in the Theoretical Physics group are working actively on. To that aim, we employ both analytical pen and paper calculations and program super-computers to solve difficult physics problems.

Our current research:

Dark matter and other new particles (Joern)

We investigate scenarios for physics beyond the standard models of particle physics and cosmology. Among other things, we are working on dark matter, supersymmetry, and the early universe.

Dynamics of the quark-gluon plasma (Konrad)

Many-body collective phenomena emerging in energetic collisions of heavy nuclei give rise to the most perfect liquid - the quark-gluon plasma. We study what very energetic and very heavy particles can teach us about the properties of this plasma using analytical and numerical tools.

Intense laser-atom interactions (Morten)

Using relativistic and nonrelativistic quantum mechanics and some contemporary programming languages (Python, MATLAB, C++, Fortran, etc.), we develop theoretical and numerical models for studying time-dependent quantum-mechanical processes governing the interaction of atoms and molecules with intense laser pulses.

Simulations of complex systems on the atomic level (Tatiana)

We apply molecular dynamics and advanced thermodynamic concepts to study the behaviour of complex systens and follow their time evolution, with the emphasis on solid-aqueous interfaces and phase transitions. Our numerical modeling make a heavy use of parallel processing. We have started to explore the application of GPU-assisted machine learning via TensorFlow for smarter MD simulations.
